[转]http post交互 json

public static String receivePost(HttpServletRequest request) throws IOException, UnsupportedEncodingException {
        
        // 读取请求内容
        BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream()));
        String line = null;
        StringBuilder sb = new StringBuilder();
        while((line = br.readLine())!=null){
            sb.append(line);
        }

        // 将资料解码
        String reqBody = sb.toString();
        return URLDecoder.decode(reqBody, HTTP.UTF_8);
    } 

 

HTTPPost发送JSON：

private static final String APPLICATION_JSON = "application/json";

private static final String CONTENT_TYPE_TEXT_JSON = "text/json";

public static void httpPostWithJSON(String url, String json) throws Exception {
// 将JSON进行UTF-8编码,以便传输中文
String encoderJson = URLEncoder.encode(json, HTTP.UTF_8);

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader(HTTP.CONTENT_TYPE, APPLICATION_JSON);

StringEntity se = new StringEntity(encoderJson);
se.setContentType(CONTENT_TYPE_TEXT_JSON);
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, APPLICATION_JSON));
httpPost.setEntity(se);
httpClient.execute(httpPost);
}
